ATTORNEY Patented June 27, 1939 CARRY BAG George W. Poppe, Brooklyn, N. Y., assignor to Equitable Paper Bag Co. Inc., Brooklyn, N. Y., a. corporation of New York 'Application December 20, 1938, Serial No. 246,795

2 Claims.

'Ihis invention relates to carry bags provided with tongues cut from the bag walls and is similar in some respects to the carry bag forming the subject matter of my application filed of even date herewith.

An object of the invention is to produce'a bag of this character in which a tongue or tongues cut from the bag walls may coact with the closing flap of the bag in such a manner as to hold said ap in closed position.`

A further object of the invention is -the production of a bag in which one of the tongues cut from the bag walls may act as a reenforcing tongue and the other as a locking tongue in cooperation with the closing ap of the bag.

A further object is the production of a bag of this character which may be made on an ordinary bag machine and at substantially the s'ame speed of an ordinary bag.

In the drawing, Figure 1 is a front elevation of the upper portion of the bag embodying the present invention; y

Figure 2 is a perspective view of the bag shown in Figure 1 but with one of the wall tongues folded upwardly;

Figure 3 is a perspective view after one of the tongues has been folded upwardly and the closing flap folded down;

Figure 4 is a front elevation of the upper central portion of the bag after the closing iiap has been folded down and the locking flap folded upwardly into locking position with the closing Ilan;

Figure 5 is a section on the line 5 5 of Figure 4; and

Figure 6 is a perspective view of a slightly modiiied form in which both of the tongues are folded upwardly into locking engagement with the closing flap of the bag.

The bag of the present invention may be formed by one of the methods disclosed in my Patent 1,798,168 and after the bag has been bottomed, the necessary punching may be accomplished by methods known to the art. As described in said patent, preliminary cuts are made in a web of paper which cuts form the side edges of the closing flap of the finished bag. The web is then folded into a tube which is subsequently severed into bag lengths.

Referring to Figure 1 of the present disclosure, such a bag includes a front wall 2 and a rear wall I, Figures 3 and 5. In the present instance, the web is folded in such a manner as to produce a wide seam and the ap 6 which closes the mouth of the bag is av prolongation of the seam wall. Paste lines indicated by the vertical dotted lines in Figure 1 are formed near the edges 'of the seam and in the center thereof. Within the seam and Vbetween' the outer paste lines, tongues 8 and Ill are cut from the bag walls. The tongue s 8 being cut from the front wall 2, contains one ply of paper while the tongue I0 cut from the seam wall contains two plies of paper, as clearly shown in Figures 5 and 6. A score line a-a is made across the bag and determines the line of 3? fold when the flap 6 is folded down onto the front wall 2 of the bag. In addition to the tongues 8 and I0 in the bag walls, the flap of the bag is provided with a cut-out or recess I2 which recess may be the same Width or somewhat nar- I rower than the width of the tongues. The tongues are hinged along their upper portion at I4, the hinge line being shorter than the width of the tongues. The tongue 8 as shown in Figures 2, 3 and 5, may constitute a reenforcing tongue, which is folded upwardly as in Figure 2. The hinge line I4, of both tongues is spaced from the score line a-a, a distance substantially equal to the length of the tongues. Therefore, when the tongue 8 is folded upwardly against the wall 2, its edge opposite the hinge line will substantially coincide with the score line, or what amounts to the same thing, the line of fold of the ap 6. This nap may then be folded down and the tongue I0 passed-through openings II in the bag walls and also folded upwardly into the recess I2, causing a locking action between the tongue and the flap 6. This locking action is brought about by reason of the shorter hinge line and by reason of the width of the cutout lin relation to the width of the tongues. The upper corners of the tongueare also rounded at I8 and the corners of the recess I2 are also rounded at 20 so that when the tongue I0 is folded upwardly to the position shown in Figure 5, the tongue Il) and flap 6 are interlocked. The tongue 8 acts as a reenforcing member while the tongue II) acts as a locking element and the rounded corners of the tongue openings tend to minimize the likelihood of a tear starting. l

Both tongues may be passed through the openings I6 and folded back into the recess or cut-out I2 as shown in Figure 6.

It will be noticed that the line of fold or score line a-a, Figure 1, includes a small portion of the bag wall 2 as indicated at 22, Figures 1 and 3. As shown in the latter figure, the tongue 8 is folded against the Wall 2 between this wall and the upper turned-over portion 22. It is obvious of course that the tongue 8 may be turned up between the turned-over portion 22 and the dan 6. A line of paste 24 may be applied across the seam adjacent the hinge line N as shown in Figure 1.

It is to be observed that the flap S may be of dlierentlengths and that the line of fold of this ap may be at the base thereof.

What I claim is:

1. A carry bag having front and back walls and a closing ap at the mouth of the bag, a reenforcing tongue and a locking tongue cut from the bag walls, said tongues hinged at their upper edges adapting them to be folded upwardly, a. cut-out in the closing flap, said reenforcing tongue adapted to be folded upwardly prior to `folding down of the ap, the locking tongue arcanes adapted to be folded upwardly into said cut against the ap when the ap is folded down.

2. A carry bag having front and back walls and a closing ap 'at the' mouth of the bag, a reenforcing tongue and a locking tongue cut from 5 GEORGE W. POPPJIE.
